Grow your meal in your mattress

Zaatari, a Syrian refugee camp in Jordan, has quickly turned into a city of 80,000 people since opening in 2012. Water can be scarce and the desert soil is too poor to cultivate anything, making nutritious food a hard resource to come by. But scientists from the University of Sheffield in England have a solution. They’re teaching refugees how to grow food by using old foam mattresses instead of soil. Host Marco Werman has the details on this unconventional garden.
